The mission of the D1 is to push the boundaries of what a modern vehicle is capable of while making its performance accessible to dedicated track enthusiasts.
The D1's 1,000hp/ton power/weight ratio is made usable by its innovative AWD system, the broad and flat torque curve of its 3.0L Hartley V8 engine, and advanced electropneumatic paddle shift system. While it would take a pro-level driver to extract this car's full potential, it can readily be driven by trackday participants of moderate experience. This usability is illustrated in our video of the D1 being tested in the tight confines of a kart track in damp conditions. The D1 features optional one-piece carbon body shell and advanced underbody aerodynamics with full-length tunnels.
To fully put the D1 in perspective it is useful to compare it to the Porsche RS Spyder LMP2 racer:
|D1||3.0L V8||430hp||1100 lb||AWD||113"||80"||68"||39"|
|RS Spyder||3.4L V8||470hp||1800 lb||RWD||183"||113"||79"||42"|
Both cars have sequential gearboxes with electronic paddle shifter and full underbody ground effects. Despite similar performance (confirmed by driver-in-the-loop simulation on several tracks such as Laguna Seca), the D1 is only 1/10th the cost of the LMP2 racer, both in initial purchase and operational costs. The D1 puts the performance of world's top racecars within reach of many dedicated enthusiasts to own and operate on a regular basis.
